采用无核密度仪检测沥青面层压实度

Test by Compaction of Asphalt Surface use PQI

通过无核密度仪在浙江舟山大陆连岛沥青路面施工过程中的应用,结合实测密度数据绘制碾压遍数与密度值的关系图表,通过分析得出:无核密度仪可以用于SMA沥青面层施工中压实度的实时、快速、无损检测,保证工程进度、确保施工质量。

In this paper, the result is gotten through the application of PQI in the asphalt pavement con- struction project of Zhejiang Zhoushan cross-sea-bridge, combined with the actual collected testing density to draw the chart of times of laminating and the reading of density, and through my analysis, that is. PQI can be used in the compaction testing of SMA type asphalt surface layer construction with the characteris- tics of real-time, fast, non-destructive. PQI is important for assuring the progress of works, and insuring the control of construction quality. And PQI has good practical application value.
